MediaReactor and MediaReactor Workstation integrate tightly with installed operating systems and applications. This section has tips and tricks on getting the most out of MediaReactor and/or MediaReactor Workstation.

Mac OS-X

Enabling legacy codecs for more output choices in QuickTime 7.4 and greater

(the original Apple article link is dead: http://support.apple.com/kb/TS1149?viewlocale=en_US&locale=en_US)

Symptoms

With QuickTime 7.4 or later installed, some older encoders (codecs) may appear to be missing export options in applications that export QuickTime files, such as Final Cut Pro or Compressor or from the export options in QuickTime Player Pro.

Resolution

Take the following steps to enable additional encoders:

Choose Apple menu > System Preferences.

Choose View > QuickTime.

Click the Advanced button.

Select the checkbox next to Show legacy encoders.

Using MediaReactor Workstation as a source reader for your own (or other) programs (OS-X)

MediaReactor Workstation provides a number of different ways to read supported file and compression types into your own programs. Here are a list of publicly available interfaces:

QuickTime Interface - MRWS provides an series of components to QuickTime including file readers, compressors, decompressors and low level data handlers that allow any program to read all the available formats through QuickTime as though they were normal MOV files

DTMediaRead Interface - This interface is a direct reader that requires an OEM agreement with Drastic. See the DTMediaRead SDK page for more information.

MkRefMov - MRWS includes a command line program called MkRefMov (Make Reference Movie). This program can make a reference movie (a small pointer only movie) for most supported files that can be read by any program supporting QuickTime MOV files. This includes new programs like Final Cut Pro X that don't normally support formats like MXF variants from Omneon, Pinnacle, Grass Valley and Avid.

Clear Avid MediaComposer Cache

Close MediaComposer

Navigate to HD/Users/Shared/AvidMediaComposer/AMA Management.

Delete the contents of the "AMA Metadata Folders" folder. The folder will be rebuilt once the software is relaunched.

Rename the "OPFrameGenerator.db" file to "OPFrameGenerator_Backup.db".

Reopen MediaComposer. Delete the file from its current bin and re-link.

Windows

Using MediaReactor Workstation as a source reader for your own (or other) programs (Windows)

MediaReactor Workstation provides a number of different ways to read supported file and compression types into your own programs. Here are a list of publicly available interfaces:

DirectShow - MRWS installs a DirectShow Filter called 'Drastic MediaReactor File Source'. This can be opened with any supported file to provide audio and video to a DirectShow filter graph

QuickTime Interface - MRWS provides a series of components for QuickTime including file readers, compressors, decompressors and low level data handlers that allow any program to read all the available formats through QuickTime as though they were normal MOV files

DTMediaRead Interface - This interface is a direct reader that requires an OEM agreement with Drastic. See the DTMediaRead SDK page for more information.

MkRefMov - MRWS includes a command line program called MkRefMov (Make Reference Movie). This program can make a reference movie (a small pointer only movie) for most supported files that can be read by any program supporting QuickTime MOV files. This includes new programs like Final Cut Pro X that don't normally support formats like MXF variants from Omneon, Pinnacle, Grass Valley and Avid.

Rename the "OPFrameGenerator.db" file to "OPFrameGenerator_Backup.db".

Reopen MediaComposer. Delete the file from its current bin and re-link.

Linking footage shot at high FPS to lower FPS project

In the bin, right click on the clip and go to Source Settings, Playback Rates. Set the Playback Frame Rate to the project's fps. Click Apply and OK. This will play the high speed clip in slow-mo.

Next, right click again on the clip and go to Audio. Check the "Delete Original Media" and click on OK. What this does is we make a copy of the audio so it's not embedded in the file and Avid does not complain about the length of the audio (which is the acquisition error). Instead it is stored in Avid Media File where it is accessed. Keep in mind this step does not delete the audio in the source file.

To get a list of all the file type available in the file codeclist.txt, use mrcmd -allTo get a list of the codecs for a file type, use mrcmd #

mkRtIndex - Make An rtin (Real Time Index) File

Usage: mkRtIndex <sourcefile> [-v]

NOTE: parameters must be in order

<sourcefile> File to be indexed.

-v Optional, verify rtIndex instead of create.

Application Specific

If your source files are on a network drive, you need enable this in Media Composer. Open a Console window (menu Tools | Console) and type 'alldrives' without the quotes and hit Return. This only needs to be done once.

Compressor

To convert from a MRWS file, create an output profile and drag the source file on top of the output profile and drop it.

Motion

To use a MRWS file in Motion, simply use the built in browser to find and select the file. Supported files will appear as a picture of one of the frames in the browser.

Adobe Media Encoder

To add a MRWS file, use the menu File | Add, or drop the file on the application.

To convert to a supported output file, once the input file is chosen an entry will appear for it in the interface. Click on the Format or Preset column link to change the output type.

QuickTime Player

To open a file in QuickTime Player (free or full version), select the File | Open File menu. In Windows you have to set the file filter to all (*.*) to see non mov/avi files.

To export a file from QuickTime Player (requires full version), select the menu File | Export... In the export dialog, select the output type and options. Type in the file name and extension to save to.
